When most people use the word podcast, they are referring to an audio podcast, which is basically like a radio show available to you on-demand so you can listen anytime and anywhere.
It’s easy to find and listen to podcast episodes from any computer or mobile device. In iOS, you can use the ‘Podcasts’ app. On Android and iOS, you can use the ‘Stitcher’ or ‘TuneIn’ apps. Or you can visit a show’s website, find an episode and click the play button.
Technically speaking, a podcast is a series of episodes of audio or video made available on the Internet for downloading to a portable media player, smart phone, computer, etc. The word is a combination of “broadcast” and “pod” from the success of the iPod.
